Expeditionary Strike Group

The Expeditionary Strike Group (ESG) is a United States Navy concept introduced in the early 1990s, based on the Naval Expeditionary Task Force. The U.S. Navy fields 9 Expeditionary Strike Groups and 10 carrier strike groups, in addition to surface action groups. ESGs allow US naval forces to provide highly movable and self-sustaining forces for missions in various parts of the globe.

The ESG concept combines the capabilities of surface action groups, submarines, and maritime patrol aircraft with those of Amphibious Ready Groups and Marine Expeditionary Units (Special Operations Capable) to provide greater combat capabilities to theater combatant commanders.[1] An Expeditionary Strike Force (ESF) integrates the CSG and ESG with the sea-basing functions provided by the Maritime Prepositioning Force (future) to provide an even more potent capability.

The United States Navy has always been involved in developing different military concepts to improve the rapid deployment of naval power and troops from one point to another. One of these concepts is the Amphibious Ready Group (ARG). The ARG consists of a group of various ships known as an Amphibious Task Force (ATF) and a Landing Force (LF) which normally consists of United States Marines and, on occasion, could consist of United States Army troops.

An ARG is composed of an Amphibious Assault Ship (LHA/LHD), an Amphibious transport dock (LPD) Ship, a Dock Landing Ship (LSD), and a Marine Expeditionary Unit (MEU) which includes a Marine Infantry battalion landing team, AV-8B Harrier II aircraft, CH-53 Sea Stallion, CH-46 Sea Knight, AH-1 Sea Cobra and UH-1 Huey helicopters.
